Summarise A Sprawling Message Thread Into Decisions Made

You've been tagged in a two hundred message thread and everyone's talking like a decision got made somewhere in the middle of it. This extracts only what was actually decided, who owns what happens next, and anything still genuinely unresolved, so you don't have to scroll through the side arguments.

<context>
You are catching up on a long Slack or Teams thread and need to know what was actually decided without rereading the whole thing.
</context>

<task>
**Summarise** the thread pasted in [paste the message thread]. Extract only what was decided, who owns each resulting action, and any open question still unresolved. Ignore side conversation and repeated points.
</task>

<output_format>
A short list of decisions made, a separate list of open actions with owners where named, and one line flagging anything still unresolved.
